Title: Optical collision avoidance system
Inventor: SNAPER ALVIN A
IPC: G01S17/46
Filed: 1987-06-19
Granted: 1991-07-02
Abstract: ABSTRACT OF THE DISCLOSURE    A proximity detecting and warning system for use in collision avoidance, particularly with aircraft. The system responds to pulsed light sources within a selected frequency band and particularly the frequency of aircraft strobe and rotating beacon light sources while disregarding any other natural steady state light sources as well as man-made light sources such as street lighting and ground lighting sources.  The system detects pulsed light sources on aircraft or vehicles within the proximity pilot or operator.  The alarm occurs when another aircraft is within the detection envelope which typically extends in an elliptical pattern around the transmitter in all directions with a detection range of up to approximately three miles. The circuit is designed to detect the strobe or rotating beacons having frequencies standardized by Federal Regulation which also requires that these sources be illuminated at all times during flight.  The proximity sensing system has a light pulse detector, a circuit for limiting the response of the device to the particular frequencies selected, and processing circuits which process received signals to discriminate between the selected frequencies and activates the visual and audible alarms.

Abstract: ABSTRACT OF THE INVENTION    A blended, stable ball clay/water slurry, wherein: 1.   the slurry comprises from about 58 to about 68 weight percent of  ball  clay, from about 42 to about 32 weight percent of water, from about 50 to about 650 parts per million (by dry weight of ball clay) of soluble  sulfate  ion,  and  from  about  0.01  to about 1.0 percent of organic  polyelectrolyte  (weight of active ingredient by weight of dry ball  clay)  with  a molecular weight of from about 1400 to about 6000; 2.  the slurry, when freshly made has a five-minute gel viscosity of  from  about  1,000  to  about  10,000  centipose,  a ten-minute gel viscosity  of  from  about  2,200  to  about  12,000  centipoise, and a twenty-minute  gel  viscosity  of  from  about  3,500  to  about 14,000 centipoise; 3.   the twenty-minute gell viscosity of a three-day old sample of the  slurry  is  no more than 50 percent greater than the twenty-minute gel  viscosity  of  the  freshly made slurry and is from about 3,500 to about 14,000 centipose; 4.  the difference between the twenty-minute gel viscosity of the slurry and its ten-minute gel viscosity is less than about 3,000 centi-poise; 5.  the difference between the twenty-minute gel viscosity of the sluffy  and  its  five-minute  gel  viscosity  is less than about 4.000 centipoise; 6.  the slurry has an initial Brookfield viscosity at 100 r.p.m. of from about 100 to about 600 centipoise; 7.  from about 30 to about 45 weight percent of the particles in the  ball  clay are smaller than 0.5 microns, from about 53 to about 69 percent of the ball clay particles are smaller than 2 microns, and from about  70  to  about  85 percent of the ball clay particles are smaller than 5 microns; 8.  the ball clay has a specific surface area of from about 16 to about 21 square meters per gram; 9.  the slurry has a settling index of at least about 0.9, a flow index  of  from  about  20  to about 30 seconds, a casting rate of from about 30 to about 60 grams, its filtrate has an optical transmission of at  least about 60 percent, and dry samples made from the slurry have a mdoulus  of  rupture  of  from about 550 to about 700 pounds per square inch; and 10.   the ball clay contains from about 50 to about 65 weight percent  of  silica  and  from  about  20 to about 35 weight percent of alumina,  and  the silics/alumina weight ratio in the ball clay is from about 2.0 to about 3Ø

Abstract: THIXOTROPIC CLAY AQUEOUS SUSPENSIONS          CONTAINING POLYACRYLIC ACID POLYMER OR COPOLYMER STABILIZERS                     ABSTRACT OF THE DISCLOSURE           The physical stability and rheological properties variations of liquid gel-like compositions based on montmoril-lonite, attapulgite, hectorite or other inorganic colloid-forming clay or other thixotropic thickener are greatly improv-ed by incorporating in the composition small amounts, such as about 1.0 weight percent, of polyacrylic acid polymers or co-polymers and their salts and small amounts, such as 0.2 or 0.4 weight percent, of calcium, magnesium, aluminum or zinc stear-ate or other polyvalent metal salt of long chain fatty acid.          The aqueous compositions containing inorganic builder salts and other functional inorganic salts, chlorine bleach, bleach-stable detergent, thixotropic thickener, and polyacrylic acid polymers and copolymers and their salts and polyvalent metal salt of a fatty acid as physical stabilizers remain stable against rheological properties variations with time and phase separation for periods in excess of twelve weeks under a wide range of temperatures.  The thixotropic properties can be retained or improved using smaller levels, such as 0.20 to 0.5%, of the clay thixotropic thickener than in the absence of the polyacrylic acid polymer or copolymer physical stabili-zer.  Use as liquid gel-like automatic dishwasher compositions are described.
